If the magnetsim gets so heavey the sun spots fade and the sun starts to dim then you know the 12/23 was the date we pasted the galactic center , and not entered it.After that it will soon get very cold world wide .Ice sheets hundreds of miles wide at the equator of the earth.

You will know The dividing line by the galactic equator , because you can not see the stars on the opposite side of the line..... you will look east and see stars , and look west and see not one star in the sky. when you pass it will just the opposite. as the years go on , the sky will fill with stars again.
